Foundries all over the world are using the Simpson Pro-Claim to inexpensively reclaim large volumes of bentonite bonded or chemically bonded sand for reuse in the molding systems resulting in significant savings in raw material and disposal costs.
Sand enters the machine and is propelled up a blast tube
with air provided by a turbo blower. As the sand accelerates
